+## 2026-02-07 - PR Hygiene and Spanish Linguistics
+**Learning:** Automatically generated files (lockfiles, PWA artifacts, logs) should be excluded from UX-focused PRs to keep the focus on relevant changes. Spanish UI text requires consistent accentuation (tildes) for professional look and feel.
+**Action:** Use 'git status' and 'git diff' to verify files before submitting. Maintain a checklist of common Spanish UI words (Mañana, más, descripción, etc.) for every review.
